...Summary...
The National Weather Service in Wilmington, with support and
assistance from Brown County Emergency Management confirmed a
brief, weak tornado initially touched down on the west side of
U.S. Highway 68 near Donley Road where a large tree was snapped
and lying across Donley Road making the road impassable for
further surveying, and a nearby residence had substantial tree and
limb damage. The tornado crossed U.S. Highway 68 causing sporadic
tree damage on the east side of the highway, and a grove of trees
several hundred yards from the road suffered more substantial
tree damage with numerous trees either uprooted or snapped. The
tornado continued northeast to Hillcrest Road, where a grove of
trees on the west side of the road showed sporadic snapped and
uprooted trees, and a residence on the east side of the road had
minor roof damage, a chimney blown off, and several uprooted and
snapped trees. The tornado began lifting further to the northeast
in the vicinity of Crawford-Day Road, where several trees and
large limbs were snapped.
The damage is consistent with wind speeds between 75 and 80 mph.
In several instances, tree damage demonstrated a cross-path
component, particularly along the first mile of the path. In
addition, the damage had well-defined lateral bounds, which
corroborated data from both the NWS WSR-88D Doppler radar in
Wilmington /KILN/, and the FAA Terminal Doppler Weather Radar
/TCVG/ near Walton, KY which showed brief, strong rotation along
this path.
The NWS in Wilmington wishes to thank Brown County Emergency
Management for support and assistance in the completion of this
survey.
